An outbreak of otitis externa was observed to affect one third of 230 swimmers using a new swimming pool within three weeks of its opening. Pseudomonas aeruginosa was grown from the water and from all of the nine swabs taken from the infected ears of the swimmers. During the same period only six other cases of otitis externa were seen in the local general practice serving 4,000 patients. The disinfection procedures were found to be defective and after they were corrected the outbreak subsided.
一个新游泳池开放三周内，观察到230名游泳者中有三分之一感染了外耳炎。从泳池水中以及从感染外耳炎的游泳者耳朵上采集的所有9份拭子中都培养出了铜绿假单胞菌。在同一时期，当地为4000名患者服务的全科诊所仅发现另外6例外耳炎病例。发现消毒程序存在缺陷，纠正后疫情得到缓解。
